I had RCM 1.12 working perfectly on our server.
Long story short, I decided to move my RCM installation to another server and upgrade to 1.1.3 in the process. That install is still having problems mainly due to getting the right selinux settings I think.
So I decided to go back to the old server (which is not using selinux) and do a fresh install of 1.1.3. Now, when I go to myserver.com/installer I just get a blank page. I did not make any changes to the original server or PHP configuration, only trying to install a new RCM. I still have the original mysql database in place. I do get a standard phpinfo page without problem.
What might be the problem here?
